INGINERATOR ATTACHMENT FOR GAS-STOVES.

Application filed November 24, 1917.

7 '0 all to ham may, concern .retercnce being had to the accoinpanylng drawings, forming part of this specification.

My invention relates to gas incinerators, and has reference to the exterior rather than the interior arrangement oi the device, and the incinerator shown in the drawings, so tar as interior construction is concerned, is the same as that oi my Patent No. 1,194,385, dated August 15, 1916.

The use oi? an incinerator in the domestic kitchen itself has not been developed to any practical extent in the art, be wause there has been no room for an incinerator of any effective size; and even ii there were room, it has been thought dangerous owing to the high. temperature necessarily developed in the incineration oi garbage. The obvious advantage oft having the point of deposit oi garbage tor incineration. in the kitchen itsel'i has led to an attempt by me to pro-- vide an incinerator and gas range comhincd. In my first device there is an inrauorator of the shape out the balance of the range set in beneath any elevated portion thereof so as to serve as a support yet insulated from the balance of the range, and having an independent flue.

The above arrangement is the sub ect matter oi? my application for patent filed May .23, 191.6, tierial No. 99,311.

The invention herein has a like object to the invention above briefly described, but is directed to the provision of an incinerating attachment for any usual gas range, whereas my former invention was complete in itself and required the purchase of a new range and incinerator complete.

The invention, directed to the above objects, will now be fully described, its advantages noted and its points of novelty duly claimed.

Fig. 8 is alike view showing the attachment for the device when used with such a stove.

Fig. 9 is a detail plan view of the device and range showing the attaching means as in Figs. 7 and 8.

The range has a top 1, with burner openings 2 therein, with the body oi: the range supported 011 legs 3. This range is shown as any well recognized type of gas cooking stove and its particular characteristics form no part of this invention. The flue of the range is quite independent of the flue for the attachment herein, and has not been shown for that reason.

The table top 1 of the stove is provided at the free side thereof with bosses 4, i, which have slots 5, 5, therein, that are generally provided in all stoves for the moimting of an extension plate. This extension plate is used for a shell for pots, pans and dishes and such like while cookingover the table top. This invention is applicable to almost every gas range, since practically all oi them are providedwith a table top which is free at one side at least, and may or may not have ovens, broilers or the like at the other. Also for the reason that thesize of the table top is so limited in domestic gas ranges, the usual practice is to provide the detachable extension plate. The invention herein is to be secured to the range by removing the extension plate and hooking the device on in its place, and thusit serves the duty of the extension plate, whether or not any additional cooking space is provided.

The attachment has a table top 6, like the table top of a stove, and beneath the top a space 7, wherein extend the burners 8. The top is provided with two openings, one for each burner, and the top is supported on the rest of the attachment by means of walls 9, 9, closed at the rear and the sides and open at the front. Any one of the side walls may be provided with a series of holes (not shown) for the escape of the products of combustion or the admission of addicooking top of the incinerator attachment and the interior of the incinerator or flue, and neither is there any communication with the interior of the range, although this latter communication might be arranged for in particular instances where the expense would be justified. The top and burners with the chamber therefor form what is known as a burner box.

The incinerator portion is of the same cross sectionas the table top, and has a complete casing 11, and a flue pipe 12 which has no inlet from the table top, but connects with the stove flue at some distance from the stove. Inside of the casing is a complete lining 13 of fire brick or other insulating material, with openings for the flue and also for the feed door 17. The flue pipe is entirely behind the table top portion of the attachment.

The incinerator and the table top portion form a unit, although they are entirely separate in every way. The gas for incineration is'led from the pipe 16 to the incinerator burner pipes 18, but otherwise there is no communication from one part of the attachment to the other.

The incinerator is supported on extendible legs 19, 19, of any desired type so that the level of the table top of the attachment may be adjusted to that of the table top of the range. The type shown comprises legs 19, slotted at 1.9 and sliding over blocks 19 on the stove. Screws 19* pass through the slots and screw into'the blocks.

For attachment to the range there are two tongues 20, 20, secured to the top of the device, the same having the slight raised portion 21 at the outer end. These tongues are mounted just under the edge of the table top and are to be setinto'slots 5, 5. In doing this theattachment is lifted slightly so as to tip the tongues into place, then righted and thelegs adjusted finally to take all strain off the tongues, with the tips 21 of the tongues lying behind the flange 21 on the top of the range.

When so attached the incinerator and cooking top attachment appear to be one piece with the range, and a .most desirable effect is produced to the eye. The adding of more cooking surface to the stove is of great value, and the incinerator, which is of course the prime objective of the invention,jis introduced into the kitchen, without outrage tothe eye, inconvenience, danger or great expense. Y r

It should be noted that the placing of the attaching tongues could be changed for various styles of stoves, although most of them have a like spacing of the slots for the extension shelf. Thus in Figs. 7, 8 and 9 is shown another form of attachment in which there are two slots 30 in the edge of the table top and a bar 31 across beneath the edge. The bar has kerfs 32 adjacent the slots, and ton nos 33 of special shape engage in the poo ets so formed. I do not claim that this form of attachment is new with me, as it is generally used for extension plates in some styles of stove. The device can be used without any tongue device at all and merely set up against the range, since the essence of the invention is the incinerator device with a separate gas burning burner box above it to form a continuation of the table top of a range and increase the cooking surface thereof.

The incinerator, while incorporated with a gas range by this invention, is quite independent of it, since it is lined with fire brick, has a separate flue and is not in communication with the table top portion of the attachment. The extendible legs make the device applicable to any store of customary design and the gas connection can be quickly and easily made by removing the cap usually found at the end of the table top 0011- nection and screwing the desired union littin in its place.

t is not intended by failing to mention equivalent structures for the details of construction of the device to exclude the claim that follows from the right to a broad and common sense construction as deduced from the plain meaning of the words therein emnloyed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A device for use in connection with gas ranges having extension shelf slots in the top thereof, comprising a casing shaped to conform to the shape of the range. a lire insulated incinerator in said casing having a flue at the rear thereof, a gas burner box in the upper part of the casing having a top, gas supply pipes on said casing adapted to be secured to the gas pipes of the range. and extendible legs for said casing adapted to stand on the floor and to hold said burner box top on a level of the range top so as to form a continuation thereof, and lugs on the burner box top to engage the extension shelf slots in the range top, whereby an incinerator and cooking attachment for gas ranges is provided which requires no modification of the range and utilizes no kitchen floor space not given to cooking.
